SIX British men were released from an In­dian prison on Tuesday (28) after a high court overturned their five-year jail sen­tences on Monday (27).

The six were collected from prison by Brit­ish embassy officials and were seen being driven away.

“Officials from the UK embassy took them after completing their paperwork,” Muruge­san, deputy inspector general of prisons in the Chennai in south India, said.

The men were acquitted by a court, along­side 29 others, of illegal possession of arms while they were on a US-operated anti-pira­cy boat.

The six Britons, three Ukrainians, 14 Esto­nians and 12 Indians were given five-year jail terms by a lower court in Tamil Nadu state in south India in January 2016.

The Indian coast guard intercepted the privately run MV Seaman Guard Ohio off the coast of Tuticorin in Tamil Nadu in October 2013. Semi-automatic weapons and thou­sands of rounds of ammunition were found on board.

The crew were charged with not having proper paperwork to carry weapons in Indi­an waters, but India has faced intense diplo­matic pressure over the case ever since.

Twenty-three of the men were detained in Chennai’s Puzhal prison, while the remain­ing 12 were at Palayamkottai Central Prison in Tirunelveli.

The Seaman Guard Ohio was chartered to protect ships crossing the Indian Ocean at a time of increased risk from pirate attacks.

The six Britons were former soldiers working as guards on the vessels.

The 35, except the Ukrainian captain and one Briton, were released on bail in 2014 on condition that they stayed in Chennai.

An Indian court quashed the charges against the crew in July 2014, but the su­preme court overturned that ruling the fol­lowing year and ordered their trial, which led to the prison terms.

US maritime security firm AdvanFort, which owns the Seaman Guard Ohio vessel, denied the charges, saying that all firearms on board were legally purchased and prop­erly documented.

The Estonian government in October summoned the Indian ambassador in Tal­linn to complain about the slow pace of the case. Britain had also made approaches to India over the case.

In London, a spokesman for prime minis­ter Theresa May said: “The government, from the prime minister down, worked hard for over four years to support the men and their families and we share their happiness at the court’s decision to give a full acquittal to each of the men.”

Britain was “working with the Indian au­thorities to discuss the next steps. We will continue to offer the men and their families consular assistance for as long as it is need­ed”, he added.

Yvonne McHugh, partner of Billy Irving, said she was “over the moon” at the news of the acquittal on Monday.

“We are just waiting to hear how soon they will be home,” she said. “I won’t be able to speak to him until he’s out of prison. We just want them home as soon as possible. I’m absolutely ecstatic and feel proud we’ve managed to do this after four years.”

The southern tip of India is close to major trading routes from Asia to Europe and many cargo ships have armed guards and vessels to deter pirates.
